New proof that asteroid impact dealt the dinosaurs a quick death blow

The title should read "New evidence that asteroid impact dealt the dinosaurs a quick death blow". Science doesn't deal in proof. It deals in
probabilities. The probability on this one however, is quite high.

Currently, the main suspect behind this catastrophe is a cosmic impact from an asteroid or comet, an idea first proposed by physicist Luis Alvarez
and his son, geologist Walter Alvarez. Scientists later found that signs of this collision seemed evident near the town of Chicxulub
(CHEEK-sheh-loob) in Mexico in the form of a gargantuan crater more than 110 miles (180 kilometers) wide. The explosion, likely caused by an
object about 6 miles (10 kilometers) across, would have released as much energy as 100 trillion tons of TNT, more than a billion times more than the
atom bombs that destroyed Hiroshima and Nagasaki.

I'd have never thought the impact that helped finish off the Dino's was right here in the America's.

(Image Caption) Near Jordan, Mont., rock layers expose the level (lower arrow) where dinosaurs and many other animals and plants went extinct. The
arrows point to coal beds that contain thin volcanic ash layers that were dated.

Although the cosmic impact and mass extinction coincided in time, Renne cautioned this does not mean the impact was the only cause of the
die-offs. For instance, dramatic climate swings in the preceding million years, including long cold snaps in the general hothouse environment of the
Cretaceous, probably brought many creatures to the brink of extinction. The volcanic eruptions behind the Deccan Traps might be one cause of these
climate variations.

The article says the date is within 11,000 years of accuracy using radiometric dating analysis. That's impressive.

To sum it up, they believe extinction was already inevitable, and had been coming on for the previous million or so years. The asteroid impact was
just the final blow that finished them off.

I think what is almost as interesting as the results of their findings, is the accuracy that has developed over time, allowing our sciences to be much
more precise in dating techniques as they're refined. Source

Yeah and then it said we all came from a cute squirrel like creature afterwards. Funny no one can find any evidence of that though aye. Oh DNA? yeah
that supports creation though. I want to see constructive step by step evidence of change from squirrel to man.

As there is none, faith is all that holds the theory together,

Wow. The faith some people have in evolution actually outweighs anyone's religious faith by an absolutely enormous measure. I'm in awe at that level
of faith, it exceeds anyone faith who believe in a creator from another time and space.

No, but seriously - this is very cool. Thanks for posting.

No nono!!! Haha, that's not right, if you think about it, we didn't go from discovering fossil fuels to sticking it in a car. The car and all
petroleum based machines are a result of playing with the originating stuff.. hey it does this pretty good, sure there's a little smoke. but who
cares!!!! fast forward to today.

If it hadn't been fossil fuels, we definitely would have tapped a different resource due to our sheer ability to break everything and find out how it
ticks.

We're only stuck on this route because as soon as we make something efficient enough for everyone to use, it becomes a reliance to us, and we can't
see any other way to do things.

We limit ourselves in old thinking and that spark of ingenuity is coming in far and few between these days.

That's sad. That you have absolutely no way to learn differently and sound petulant in your inability to think logically.

I wonder if it's because you don't want to even look at the plethora of evidence supporting evolution.. feel annoyed that everyone laughs at god and
his feeble earth bound minions, or because you truly just don't have the capacity to look at the evidence and see it for what it is.

Unlike god and his faery dust, the things that give evolution tangible credibility are all around you in the very things that you see and touch every
single day.

Sure it's a faith of sorts, but one born from research, investigation and our ability to reason. God turns all of that into nonsense because faith
drives gods car. Without faith in god, there is no evidence, no strand of logic, no tangible thing that says he was ever here.

They have never found a dinosaur fossil in the KT boundary. Until they do, the asteroid could not have killed them. They were already dead. Up to it
is not in it. None have been found in it. If a world wide event happens and kills millions upon millions of animals, one would expect there to be
fossils in the layer made by the event. But there are none.

Dinosaurs were gone before the impact. Killed by gases let out by volcanic eruptions. This ruined the environment. Acid rain from the volcanoes killed
too much vegetation and that broke the food web. The animals starved. The acid rain killed many kinds of plants too.

When the meteor hit there were no dinosaurs left to kill. Or they could have been very few and on the brink of destruction and the meteorite just
finished them off. But there is no evidence for that. The evidence says they were gone.

Seriously. I am actually in awe of that level of faith.

Its not exactly faith, more like a very educated guess based on available evidence.

It differs from religion in that religious faith is based on a book which has been proven to be manmade and to anyone who isnt brainwashed it obvious
its been edited and made to fit an agenda.

Also no one is gonna kill anyone over the details of exactly how it happened or what the rules of it are.
